Industrial General Permit Order

E. NEC Limitations

1. NEC coverage is available on a facility-wide basis only, not for individual
outfalls. If a facility has industrial storm water discharges from one or more
drainage areas that require NOI coverage, Dischargers shall register for
NOI coverage for the entire facility through SMARTS in accordance with
Section II.B.2. Any drainage areas on that facility that would otherwise
qualify for NEC coverage may be specially addressed in the facility SWPPP
by including an NEC Checklist and a certification statement demonstrating
that those drainage areas of the facility have been evaluated; and that none
of the Industrial Materials or Activities listed in subsection C above are, or
will be in the foreseeable future, exposed to precipitation.

2. If circumstances change and Industrial Materials and Activities become
exposed to rain, snow, snowmelt, and/or runoff, the conditions for this
exclusion shall no longer apply. In such cases, the Discharger may be
subject to enforcement for discharging without a permit. A Discharger with
NEC coverage that anticipates changes in circumstances should register for
NOI coverage at least seven (7) days before anticipated exposure.

3. The Regional Water Board may deny NEC coverage and require NOI
coverage upon determining that:

a. Storm water is exposed to Industrial Materials and Activities; and/or

b. The discharge has a reasonable potential to cause or contribute to an
exceedance of an applicable water quality standards.

F. NEC Permit Registration Documents Required for Initial NEC Coverage

A Discharger shall submit via SMARTS the following PRDs for NEC coverage
to document the applicability of the conditional exclusion:

1. The NEC form, which includes:

a. The legal name, postal address, telephone number, and e-mail address
of the Discharger;

b. The facility business name and physical mailing address, the county
name, and a description of the facility location if the facility does not
have a physical mailing address; and,

c. Certification by the Discharger that all PRDs submitted are correct and
true and the conditions of no exposure have been met.

2. An NEC Checklist prepared by the Discharger demonstrating that the facility
has been evaluated; and that none of the following industrial materials or
activities are, or will be in the foreseeable future, exposed to precipitation:
